Acceptance Testing

General info

Complete suite of testing facilities

Minitest is small, fast, and it aims to make tests clean and readable. It supports test-driven development (TDD), behavior-driven development (BDD), mocking, and benchmarking.

JGiven is a BDD tool for Java in plain java.

With JGiven Developers write scenarios in plain Java using a fluent, domain-specific API, JGiven generates reports that are readable by domain experts.
xUnit
Set of frameworks originating from SUnit (Smalltalk's testing framework). They share similar structure and functionality.

Yes

MiniTest is an xUnit style framework in that is has assertion functions in the style of xUnit/TDD

No

Client-side
Allows testing code execution on the client, such as a web browser

No

Yes

You can test UI functionality or behaviour by writing scenarios that cover front-end behaviour
Server-side
Allows testing the bahovior of a server-side code

Yes

You can test various back-end components

Yes

You can write 'scenarios' to test server-side behaviours
Fixtures
Allows defining a fixed, specific states of data (fixtures) that are test-local. This ensures specific environment for a single test

Yes

Minitest supports test fixture functions

Group fixtures
Allows defining a fixed, specific states of data for a group of tests (group-fixtures). This ensures specific environment for a given group of tests.

Yes

Minitest has group fixtures

N/A

Generators
Supports data generators for tests. Data generators generate input data for test. The test is then run for each input data produced in this way.

Mocks
Mocks are objects that simulate the behavior of real objects. Using mocks allows testing some part of the code in isolation (with other parts mocked when needed)

Yes

Mocking is available through the Minitest::Mock class which is a simple and clean mock object framework

Yes

You can use third party libraries such as JMock and JMockit to mock objects and functions
Grouping
Allows organizing tests in groups

Yes

Allows grouping by nested Ruby classes. RSpec-like "context" method is available for spec syntax through the minitest-spec-context extension gem
